Transcript of AS Biology - teignmouth.devon.sch.uk€¦ · Web viewThis unit covers some of the key science...
The Applied Science course is taught in units, as below:
Unit 1: Principles and Applications of Science I (Exam)This unit covers some of the key science concepts in biology, chemistry and physics.
Unit 4: Practical Scientific Procedures andTechniques (Assignments)This unit covers quantitative laboratory techniques, calibration, chromatography, calorimetry and laboratory safety, which are relevant to the chemical and life science industries.
Unit 3: Science Investigation Skills (Marked Investigation)This unit covers the stages involved and the skills needed in planning a scientific investigation: how to record, interpret, draw scientific conclusions and evaluate.
Unit 8: Physiology of Human Body Systems (Assignments)This unit will focus on the physiological make up of three human body systems (musculoskeletal, lymphatic and digestive), how the systems function and what occurs during dysfunction.
Overall, the assessment is 25% exam, 33% supervised assessment and 42% coursework
